Birdathon is Houston Audubon's annual spring fundraiser where participants compete to count as many bird species as possible in a 24-hour period while fundraising for bird conservation. All contributions support Houston Audubon's mission to advance the conservation of birds and positively impact their supporting environments.

The 2021 Birdathon birding period lasts from March 22 - May 7. Teams and individuals may select a consecutive 24-hour period to identify as many bird species as possible anywhere in Texas! You can participate in Birdathon individually, in teams, or virtual teams with members in different locations birding at the same time.
